The side blank may be an endless strip having-score lines 1, 1, 1, 1,providing hingecorners connecting sides5, 5, 5, 5, said sides beingclosed into an endless side wallproviding structure byadhesive 9connecting flap 10 with the end of the side 5.

' In fruit and berry boxes or structures rest upon that of the lowerbox, and itis still desirable to have the boxes carry heaping measure, acountersink for the bottom is desirable so that the bottom positions upinto the sidewalls. To this end, foldable bottom section blanks areprovide Diverging scoring lines 11, 12., 11, define mounting flaps 13with intermediate bottom forming sections 14. or" 14. 'Adhesive 15 mayassemble these flaps 13 with adjacent terminal pairof sides 5, 5, as'toone section and the'other sides 5,5, as to the othersection. Thesebottom sections, accordingly, have hinge connections 11 approximatingbase and altitude therefor with hypotenuse approximating free edge .16or connecting edges 16'. In smaller containers wherein the material isnot fine for sitting out, intermediate cut away portions 17 in the scorelines 12 tend to minimize knock-down strain between the sides 5, 5 ofeach bottom section. When desired symmetry and convenience for readyslipping into overlapping relation is effected by cut away portions- 18adjacent the ends of the hypotenuse approximating edge 16.

' This knock-down box as assembled may be transported to the place ofuse or kept in storage in flat condition occupying a minimum otspace.When it is desired to use the box, it s in condition for quick easysetting up in a self-locking position as the diagonal corners 1, 1,which are in the region of the hypotenuse approximating'edge 16 of thefoldable bot-tom section, are moved away from each other,theseprojecting foldable sections readily pass, one by the other, intooverlapping position to bring the respective sections 14:, 14 as onopposite sides of the score lines. 12 into a common plane parallel tothe plan'e'of the adjacent section. Due to this overlapping, one withthe other, there is stiffening for the bottom due to the edges 16, 16'.adjacent the cut away portions 18 riding close to the hinge portions 11of the opposing section; In berry or fruit box types of structure, thislocking is sufiicient to carry the load for the container.

In this particular branch of use, these boxes may be stacked as filledone directly' over the other independently of any intermediate slats orspacers so that the countersunk bottom boxes may be stacked to thedesired heights in the fruit crates with the wherein the contents of onebox should not a foldable bottom section (Figs. 7, 8) dibottom.Furthermore, dies may be had for bottom cutting with one edge, the top,adjustable for variable size'box capacity with rectly hinged on thesides as integral connection instead of the attached hinge con,- nectionof the countersunk bottom, box. To

The sides 27, 28, remote from the score line 26 have score lines33defining flaps 34 of the respective sides 20, 21.
